arm-sveARM SVE skill for scalable vector extension programming. An agent skill from mohitmishra786/low-level-dev-skills.
Arm Sve is an agent skill from mohitmishra786/low-level-dev-skills. ARM SVE skill for scalable vector extension programming. Use when writing SVE intrinsics, predicate registers, VLA loops with svcnt, auto-vectorization with -march=armv9-a+sve2, or debugging SVE in GDB. Activates on queries about SVE, SVE2, predicate registers, svld1, svcnt, armsve.h, or Graviton SVE.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Debugging. It works with Amazon Web Services. The repository describes itself as: A curated suite of AI agent skills for systems and low-level programming with C/C++, Rust, and Zig toolchains, covering compilers, debuggers, profilers, build systems…. The licence is MIT.
10 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit bdc5847. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash, c and gdb).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Arm Sve loads about 1.4k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 374 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Migration checklist
├── Replace fixed loops (i += 4) with svcntw() strides
├── Add svwhilelt predicates for tails
├── Use _x (merging) vs _z (zeroing) predicated ops intentionally
└── Test on multiple VL hardware or use QEMU sve-max-vq# QEMU SVE emulation
qemu-aarch64 -cpu max ./saxpy| Symptom | Cause | Fix |
|---|---|---|
| Illegal instruction | No SVE hardware | Check cpuinfo; use NEON fallback |
| Wrong results in tail | Inactive lanes modified | Use _x predicated ops, not unpredicated |
| Slower than NEON | Short arrays | SVE setup cost; scalar for n < VL |
| Auto-vec failed | Unknown trip count | -fno-trapping-math; pragma simd |
| Apple M3 build fails | No SVE on M3 | Guard with __ARM_FEATURE_SVE |
| GDB can't print Z regs | Old GDB | Upgrade GDB; run on SVE hardware |

SKILL.md names no scripts, command-line tools or credentials: Arm Sve is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Arm Sve is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
